Port Diameter
Enter the valve port diameter (PORT_DIAMETER
[84.3]) in inches or mm.
Port Type
Enter the valve port type (PORT_TYPE [84.4]).
Flow Direction
Enter the flow direction (FLOWDIRECTION [84.5])
through the valve.
Push Down To
Enter the effect on valve movement when the stem is
moved down (PUSH_DOWN_TO [84.6]).
Flow Tends To
Enter the effect on valve travel with increasing flow
(FLOW_TENDS_TO [84.7]).
Unbalanced Area
Enter the valve unbalanced area
(UNBALANCED_AREA [84.8]) in in
2
or mm
2
.
Actuator
Actuator Manufacturer
Enter the manufacturer’s identification number
(ACT_MAN_ID [22]) of the actuator on which the
instrument is mounted. Select from the drop-down list
or enter the manufacturer’s identification number as
defined by the Fieldbus Foundation. For Fisher, the
manufacturer ID hex value is 005100.
Actuator Model Number
Enter the type number for the actuator
(ACT_MODEL_NUM [23]) on which the instrument is
mounted.
Actuator Style
Select the Actuator Style (ACTUATOR_STYLE
[42.1]), spring & diaphragm, piston double-acting
without spring, piston single-acting with spring, or
piston double-acting with spring.
Actuator Serial Number
Enter the serial number (ACT_SN [24]) for the
actuator on which the instrument is mounted.
Actuator Size
Enter the size of the actuator (ACTUATOR_SIZE
[85.1]) on which the instrument is mounted.
Actuator Fail Action
Sets actuator action to be performed upon loss of
actuator air pressure (ACT_FAIL_ACTION [21]).
View / Edit Feedback Connection
Refer to table 4-10 for Feedback Connection options.
Choose the assembly that matches the actuator travel
range.
Note
As a general rule, do not use less than
60% of the magnet assembly travel
range for full travel measurement.
Performance will decrease as the
assembly is increasingly subranged.
The linear magnet assemblies have a
valid travel range indicated by arrows
molded into the piece. This means that
the hall sensor (on the back of the
DVC6200f housing) has to remain
within this range throughout the entire
valve travel. See figure 2-3. The linear
magnet assemblies are symmetrical.
Either end may be up.
Travel Sensor Motion
Note
The Travel Sensor Motion is set
automatically by Device Setup, or
during the Auto Calibration procedure.
